I Guess The Motive Wasn’t That Unclear After All?

 But now, they appear to be sure of the motive - so sure they've applied to have his business closed down:

The nameless entrance on Dynevor Road, behind Good Pizza, has been blocked by police tape with a police car parked outside since the shooting. A closure order has been placed on the black door.

Apparently due to the threat of reprisals from his gangster opponebts. 

Mr Ozmen was reportedly part of the Hackney Bombers organised crime group who have been at war with rivals the Tottenham Turks.

Ah, London. so vibrant, so enriched. So much better now than when boring old native Jack 'The Hat' McVitie  was being murdered by boring old native Reggie Kray, eh?

DCI Dave Whellams, who is leading the investigation, previously said: “We continue to appeal for witnesses to come forward following the fatal shooting of Erdal. He was a father-of-one and was deeply loved by his family.”

They always are, Dave. And so very good to their dear old mum.
